BRACELET.

SPECIFICATION forming part of Letters Patent No. 253,612, dated February14, 1882' Application filed December 31, 18B]. (No model.)

T 0 all whom it may concern Be it known that I, WILLE'J A. JoHNsoN, ofPhenix, in the county of Kent and State of Rhode Island, have inventedan Improvement in Bracelets, of which the following is a specification.

My invention consists in an improved concealed hinge-joint for flatbracelets, and also in an improved bracelet-clasp, as hereinafter fullyset forth.

Figure 1 represents an elevation of the partially-opened bracelet withthe front plate removed to show the catch mechanism. Fig. 2 representsthe same with the bracelet closed. Fig. 3 is a similar view, showing thehinge of the bracelet, the front plate being removed. Figs. 4 and 5 aredetail sections taken in the line as m of Fig. 3.

In the drawings, A A represent the inner or back plates of the bracelet,having their edges a a turned outward to cover the edges of the frontplates, B B. The separatelyformed hinge O is soldered to the outer sideof the back plates, A A, so that the joint I) of the hinge will belocated at one side of the joint, between the plates A A, and the np-'turned flange a of the plate A is hollowed out, and the flanges a of theplate A are oppositely rounded, with a radius centering at the axis ofthe joint b of the hinge (l, which sccures the two plates to each other.The hinge 0 being thus located at a suitable distance from the jointbetween the plates A A, allows the concealment of the hinge-joint by thefront plate B, and still allows the proper movement of the joint foropening the bracelet, the plate B passing under the plate 13 of the0pposite arm of the bracelet. This concealment of the hinge-joint is avery desirable feature in flat bracelets, for the reason that the hingemay be made of unfinished base metal without.

detriment to the bracelet, and the bracelet so constructed presents asmooth, uniform external appearance, and the rivet-wire which disfiguresordinary bracelets is enti rely concealed.

To the plate A, at the opening side of the bracelet, is secured the flatcatch-stud D, pro vided on its inner edge with the notch d and on itsouter edge with the spring E, and to the plate A, at the opposite arm ofthe bracelet, is secured the catch a. IVheu the two ends of the braceletare brought together the catch 0 of one arm engages with the notch d ofthe other, thus holding the two arms securely; and to unclasp thebracelet the two arms are to be pressed edgewise with each other, so asto bend back the spring E toward the catch-stud I), thus releasing thecatch 0 from the notch d, allowing the bracelet to be opened. This formof concealed clasp for bracelets leaves the exterior of the front platefree from projections, and the bracelet thus presents a smooth, uniformexternal appearance.

I claim as my invention- 1. In a bracelet, the combination of the backand front plate with a separately-formed hingejoiut placed to one sideof the joint between the two arms of the bracelet, and concealed fromview within the inner and outer plates and edges of the bracelet,substantially as de scribed.

2. In a bracelet, the combination of the flat catch-stud D, provided atits edges with a notch d, and spring E, attached to one arm of thebracelet, with the catch 0, attached to the end of the opposite arm, tobe operated by the edgewise movement of the arms, substantially asdescribed.
